[Comp] Health Comp (Demo)

Overview

AC_HealthComp is an Actor Component designed to manage the health system of its owning Actor (typically a character or any damageable entity). It initializes the health value, listens for damage events applied to the owner, updates the current health accordingly, and handles death logic. This component centralizes health management and provides hooks for reacting to health changes and death events.

Variables

Variable Name	Type	Purpose
CurrentHealth	Float	Tracks the current health value of the owner. It is initialized to MaxHealth and updated when damage is applied.
MaxHealth	Float	Defines the maximum health the owner can have. Used to initialize CurrentHealth and clamp its value.
OnHealthChanged	Delegate (Event)	Intended to broadcast health changes to listeners. Not currently used in the Blueprint but designed for external binding to respond to health updates.

Event Graph Breakdown

Event: Begin Play

Purpose: Initialize health and set up damage event binding.
Behavior:
- Sets CurrentHealth to the value of MaxHealth at the start of gameplay.
- Registers a delegate to the owner's OnTakeAnyDamage event, binding it to the custom event OnOwnerTakeAnyDamage. This ensures the component is notified whenever the owner takes damage.

Event: OnOwnerTakeAnyDamage (Custom Event)

Purpose: Responds to damage events received by the owner.
Behavior:
- Calls the ApplyDamage function, passing the damage amount received.
- Acts as an intermediary to process damage through the component's logic.

Event: OwnerDeath (Custom Event)

Purpose: Handles the owner's death.
Behavior:
- Uses a Do Once node to ensure death logic executes only once.
- Prints a message to the screen and log indicating the owner is dead.
- Contains a Switch Has Authority node (details truncated), likely to differentiate behavior between server and client or to trigger further death-related logic.

Functions

Function: OnRep_CurrentHealth

Purpose: Replication notification handler for CurrentHealth.
